[ruby-dev:50093] [Ruby trunk Bug#13489] "make test-all" fails on macOS with case-sensitive filesystem

Issue #13489 has been updated by watson1978 (Shizuo Fujita).


以下の変更をテストに加え `#include <Ruby/ruby.h>` を生成することで、`conftest.c` のコンパイルエラーは解消しました。

```

テスト結果は以下のようになりました。case sensitive ではない Filesystem を利用している macOS では、
上記の変更を加えてもエラーは無かったので、まだ何か問題があるようです。

----------------------------------------
普段使用している macOS は HFS+ case-sensitive でフォーマットしています。
"make test-all" をそのマシン上で実行すると以下のようなエラーが発生し、
どうやら conftest.c でのコンパイルエラーが原因のようです。

conftest.c には

~~~
#include <Ruby/Ruby.h>
~~~

 という行が生成されるらしいのですが、
case-sensitive なファイルシステムではそのファイルパスを見つけることができません。

~~~
#include <ruby/ruby.h>
~~~
と生成されるべきかと思います。

https://github.com/ruby/ruby/blob/3e92b635fb5422207b7bbdc924e292e51e21f040/test/mkmf/test_framework.rb#L24-L33
の have_framework("Ruby") でinclude文が生成されているのかと思われます。
